Normal penis length for boys

Generally speaking, due to differences in race, personal physical fitness, and genetic factors, the length of everyone's penis is not exactly the same. However, a normal man's penis should be within a reasonable range to consider normal physiological needs. Let's discuss what is the normal length of a boy's penis?

In clinical medicine, if the length of a man's penis is 2.5cm or more shorter than the average length of a normal person of the same age, it can be considered as a short penis. However, the appearance and anatomical structure of a short penis are the same as those of an ordinary person. In Chinese men, after adulthood, the length of the penis is about 5 to 6cm when flaccid, and about 11 to 13cm when erect. Under normal circumstances, an adult's penis can be diagnosed as short if it is less than 4cm when flaccid or less than 9.5cm when erect. The causes of short penis are many and complicated, and the understanding of its causes is not deep. Although some drugs and surgical methods can be used for treatment at this stage, the overall effect is poor and cannot be eradicated.

1. What are the key clinical symptoms of short penis?

1. The male genitals are shorter and more compact than those of normal growth and development of people of the same age, and the length is shortened to 2.5cm or more.

2. The appearance of the male genitals is normal, erections are normal, and male sexual function is normal.

3. A full-body physical examination shows no scrotal or testicular deformities, and some patients may have a smaller prostate.

2. What are the common ways to diagnose a short penis?

The causes of short penis are very complex and there is no definitive name, but it can be attributed to the external manifestations of a variety of diseases. Proper diagnosis requires a thorough understanding of the medical history and a full range of auxiliary examinations. The medical history should include the medical history of abnormal growth and development of the reproductive organs, the clinical manifestations related to the two, family history, etc. Auxiliary examinations should focus on observing the length of the penis when it is flaccid and erect, and the size of the testicles, and also pay attention to the patient's appearance and clinical symptoms.

1. Laboratory examination and diagnosis. Carry out basic thyroid function measurement, and auxiliary measurement can also be done for blood sugar, potassium, sodium, etc., and children's growth hormone test can be carried out when necessary.

2. Basic imaging diagnostic examinations. Basic CT or MRI examinations are indispensable. Based on these imaging diagnostic examinations, the hypothalamus and pituitary glands can be diagnosed for abnormalities.

3. Analyze chromosome karyotype. If basic tests cannot make a diagnosis, basic chromosome karyotype tests can be performed if conditions permit to check whether there are abnormalities in the chromosomes.
